(Not so) Pro tip: I accidentally joined the Forest Hunter covenant before killing Pharis, ignoring that then she'd become friendly. Attacking her in that situation would betray the covenant and cause me some headaches fixing that. Kicks (movement forward + normal attack with most weapons) don't turn NPC hostiles. So I kicked her once and again until I threw her off a cliff. Reloaded the game, and the loot was where she was standing. No hostility, no covenant betrayal, all profit! - This was done in DS Remastered Edition -

The first time Pharis walked off the cliff and I didn't get the bow. After leaving the covenant, rejoining, attacking members and getting absolved by Oswald then rejoining again there was a gold soul on the ground where Pharis usually stands. I got the bow, her hat, and twin humanity. Not sure of you have to do all that; maybe leaving and rejoining is enough to reset her.
